摘要
为探讨应用牛催乳素促进乳腺生物反应器高效表达外源蛋白（如人乳铁蛋白、人血小板生成素）的可行性，构建两种牛催乳素和外源基因乳腺共表达载体。一种为牛催乳素基因和外源基因共用一个6.7 kb山羊β-酪蛋白启动子启动转录，两个基因以内部核糖体进入位点(IRES)连接；另一种为外源基因利用6.7 kb山羊β－酪蛋白启动子，催乳素基因利用2.0 kb山羊β-酪蛋白启动子，分别转录。脂质体转染后，RT...
摘要通过长距离PCR从山羊基因组DNA分两段扩增山羊β乳球蛋白（β-lactoglobulin,BLG）基因，扩增出的两个片段分别克隆到T载体上，利用BLG基因序列自身存在的NarI单酶切位点进行拼接，获得了全长为7.2kb的山羊BLG基因克隆，并构建了它的真核表达载体，经酶切鉴定和序列分析证实了克隆的正确性。用线性化的BLG基因显微注射小鼠受精卵以建立转基因鼠，经PCR和Southern印迹分析...
